FIRE-EXTINGUISHER.

Appli-cation filed July 28, 1915.

To all LU/1.0m t may Concern Bc it known that l, RAYMOND "l A. loxns, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful improvements in Fire- Extinguishers; and I do hereby declare the following to be a full, clear, and exact -description oi' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to new and useful improvements in fire xtinguishers and the principal object oit the invention is to provide a device wherein the chemicals contained in the various compartments may be agitated7 either mechanically or automatically so as to keep the saine at their maximum strength, thereby guaranteeing the greatest possible efficiency of the extinguisher.

Another object of the invention is toprovidea fire extinguisher, which will be kept at all times at its maximum elliciency since the construction thereof will allow the user to agitate the solution within the extinguisher periodically to prevent precipitation and crystallization of the chemicals so as to avcid depreciation of the strength of the solutions and the eiliciency of the extinguisher.

Another object of the invention is to provide a device wherein the life 01": the extinguisher may be increased indefinitely as the frequent agitation of the various chemicals within the same will prevent deterioration of the material from which the extinguisher is constructed and also-'avoiddetcrioration of the chemicals.

Another object of this invention is to prolvide a device which may be transported without danger to the user as with the present day extinguisher if the user should tilt them while transp'ortating it the same will discharge and if any of the solution should strike the eyes it would completely destroy the sight. My extinguisher does away with this danger.

Another object of this invention is to provide an airtight closure for the acid container so as to prevent the acid from absorbing the fumes or `water'irom the soda solution whichwould render the acid into carbon dioxid and then when the extinguisher would be placed in serv.ice,it would be ef .no value as the aci-,fl haclaiready been Specification of Letters Patent.

decomposed having absorbed the carbonates from the soda solution, and thus the effect thereof would have been destroyed.

A further object of the invention is to provide an extinguisher wherein the mixing of the chemicals is effected manually so as to keep the same constantly in solution by agitation of the extinguisher without endangering the discharge of the extinguisher by the mingling of the solutions.

l-leretoiore it has been the usual practice to place one of the solutions in the body of the extinguisherand the other solution in a capsule contained in the body and when the extinguisher was agitated or turned over, the capsule would be broken, thereby causllatented Dec. l2, 1916..

ing the two chemicals to mix and operating i the extinguisher. This invention is designed to avoid possibility of accidental discharge of the extinguisher througa agitation as the chemicals will not mix except upon the proper manipulation of the valves controlling the mixing of the chemicals. 4 A further object of the invention is to provide a positive closure for the acid chamber which y cannot become accidentally opened, thereby insuring the user against the discharge of the extinguisher prematurely.

Still another object of the invention is to provide an extinguisher in which it is possible to discontinue the operation at any time by stopping the flow oit' acid into the soda solution, thereby preventing further decomposition of the chemicals and retaining a part of the solution so that the device may be used at intervals without necessitat` ing the recharging eac-h time the same is placed in operation. l

Still another object of the invention is to provide a novel form of valve for closing the acid container which will effectively prevent leakage of the contents of theextinguisher when the same is inverted and which is so designed as to discontinue the operation of the extinguisher at any time without entirely exhausting the supply of chemicals contained therein.

With these and other objects invicw the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a perspective view di a lire extinguisher constructed in accordance with this invention. 2 a fragmentary ,y

Fig. 7 is a detail view of .a modified form of the controlling plunger. Fig. 8 is a view ofl a modified form of valve and controlling means. Fig. 9 is a perspective view of the controlling lever used in i Fig. 8. Fig. 10 is a further modification of valveand controlling` means. Fig. 11 is a n top plan view of Fig. 10. Fig. 12 is a view Vof .aY still further Vmodilied form of valve and controlling means'.V Fig. 18 is a fragmentary top yplan view of Fig; 12. Fig.' 14 is a vertical sectional view through the extinguisher, and Fig. 15 is a plan view of the interior of the bottom of the device, showring the agitator in detail.

Referring to the -drawings by characters of reference,tlie numeral 1 designates as an entirety the extinguisher which comprises the cylindrical shellQ which is formed of seamless material and provided with the bottom 3, which is concave as clearly shown in the drawings. This bottom is formed integral with the shell 2, and extending thereacross is a suitable rod 4t which forms a handie by meansV of which the device may be moved when in its inverted position. Riveted or otherwise secured as at 5 near the upper edge of the cylindrical shell 2, but spaced downwardly therefrom for a. short distance toform the wall 6, is a suitable band 7 having the inwardly projecting flange 8 formed at, itsV upper end. rThis fiange projects inwardly for a short distance and terminates in the upstanding flange 9, which extends vertically to a point in a hori- .zontal plane with the upper edge of the wall 6 and is then curved inwardly to form a dome 10 having the collar 11 formed at its upper end, and this collar is externally screw threaded as clearly shown. The portion 6 of the shell 2 and the flanges 8 and 9 form a chamber for the reception of the hose, which chamber extends annularly so that the dome practically forms a core on which-the hose may be wound. Extending through the flange 8 near the band 7 is an aperture 12 through-which the upturned end 13 of the outlet pipe 14 extends. This upturned end is bent angularly as at 15 and is arranged to 'extend into the hose 16 and hold the same onthe extension 15, thereby forming a `connection ybetweenthe hose and the interior of the extinguisher. The end of the tube 14 opposite the upturned portion 13 is bent upwardly as at 17 to conform to the shape of' the flange 9 and is again bent inwardly as at 18 to conform to the shape of the dome 10. This extension 1S is secured to the dome 10 b y means of a clamp or other suitable securing means 19, and it will thus be seen that when the device is in its inverted position, substantially the entire amount ol liquid contained within the extinguisher will be forced outwardly through the hose, since the opening thereot is located at the lowermost point of the receptacle. A suitable cut-away portion 2,() is formed in the wall 6 and is provided at a point in radial alinement with the tube 1lfor the purpose of enabling the user to remove the hose from the portion 15 and substitute a new hose therefor should the original become worn or otherwise unfit for use.

The cap used in connection with the dcvice is designated lgenerally by the numeral 21 and comprises the disk 22 having formed thereon the downturned, internally screw threaded flange Q3 which extends around the periphery and engages the threads on the flange 11. A suitable central threaded aperture 2l is formed in the disk 22 and is surrounded by the fiange 25 which is internally screw threaded. Riveted or otherwise secured as at 26 to the disk Q2 are the depending arms 27 to which-are pivotally secured as at 2S the arms 29, the lower ends of which are pivotally secured as at to the bottle holder designated generally by the numeral 31. This bottle holder is best illustrated in Figs. 2, 3, el, and 5, and comprises the metal shell 32 having the upper end inturned as at 33 and provided with the cushion 34. The lower end is formed with the bayonet slots 35 in which the cross arms 3G engage to hold the bottle in place. The body 32 is formed with a pair of diametrically opposed, longitudinal openings 37 which are provided to enable the user to determine the quantity of liquid within the bottle 3S.

In order to close the mouth of the bottle, there is provided the washer or disk o9 which is mounted at the end of the stem 40, which stem is provided with the external screw threads 41, which threads copcrate with the internal threads in the collar Q5 in hold ing the stem in place. The upper end oi the stem 40 terminates in the hand-hold 4-2 and when the stem is threaded into the container, it will be seen that the washer will engage the upper end of the neck of the bottle, and when the stem is withdrawn and the bottle neck is opened, it will be apparent that the washer will engage the under edge of the collar 25 and thereby form a closure which will prevent .the leakage of liquid around .the Stem,-

In the modilied form of controller, the washer 39 is carried on a smooth stem 43 having formed intermediate its ends the lug 44 which engages beneath the keeper 45 formed on the upper face of the disk 22 and thus holds the washer 39 against the bottleneck. When this device is released, the handhold 4G is grasped and the stem given a partial turn so that the lug 44 will be brought from beneath the keeper 45 and it will thus be seen that the stem may be pulled outwardly until the washer 39 engages the lower edge of the collar 25 and will thus uncover the mouth of the bottle, thereby permitting the liquid to flow therefrom as soon as the device is in place.

In the modified form of controller illustrated in Fig. 8, the washer 39 is carried on a smooth stem designated by the numeral 47, the upper end of which is reduced and has pivotally secured thereto as at 48, the bifurcated end 49 of thelever 50. rlhe opposite end of this lever is provided with a downturned hook 51 and the ends of the bifurcated portion o f the lever provided with the arcuate cam face 52. It will thus be seen that when the lever is thrown upwardly, the cam face will engage the body 22a of the top or cap and thereby pull the washer 39 from its seat against the bottle neck 3S. In order to normally hold the valve 39 seated, the spring' 53 is provided and surrounds the stem 47 and one end of the spring abuts the under side of the body 22aof the hood, while the lower end of the spring abuts the upper face of the washer 39. 1t will be noted that in this form the collar 25a is smooth, both on its interior and exterior and is spaced from its stem for a short distance to provide a chamber for the reception of the spring.

lin the further modification illustrated in Fig. 10 the collar 25b is spaced in the usual way and the stem is designated by the numeral 54 and is constructed similar to the stem 43. r1`he upper end of the stem however is provided with the cross bar 55 which in turn is provided on its upper face .with the thumb piece 56 and the top 22b is formed at diametrically opposite points with the upstanding members 57 provided with the inclined cam faces 58 and it will be seen that when the cross bar 55 is turned, the same will engage the cam faces and thereby ride up the same until they engage the upstanding portions 57, thus holding the valve 39 upwardly against the tension of the spring 53.

1n the modification shown in Fig. 12, the upper end of the valve stem is bifurcated as at 59 and the top 22 is formed with a pair of relatively semi-circular openings disposed with their flat faces in spaced parallel. relation through which the upper ends of the :arms formed by .the bifurcation extends? 1t will thus be seen that a bar 60 will be formed between the openings. The cam face G1 of the lever 62 which is pivoted as'at 63 between the bifurcated ends of the stem bears against this bar. 1t will thus be seen that when the lever is in the position illustrated in Figs. 12 and 13, the valve will be lifted from the mouth of the bottle neck so that it engages the lower edge of the tubular portion 25, thereby permitting the liquid toiiow from the bottle and into the container. The modified form of valve in connection with this device is carried at the lower end of the stem hereinbefore described which is designated by the numeral 64 and is provided at its lower end with the enlargement 65. The valve comprises the disk 66 having the frusto-conical portion 67 formed on its under side which .forms a plug to fit within the bottle neck and it will be seen that when the valve is seated under the pressure of the spring, surrounding the stem 64 any escape of liquid from the bottle will be prevented.

r1`he bottom of the shell 2 is designated by the numeral 3 and is formed with a central opening 79 surrounding which is a hollow boss 8O which is preferably externally screw threaded as clearly shown in the drawing.

Extending through the opening 79 in the hollow boss 80 is the shaft 81 provided at its outer end with the squared portion 82 on which the handle 83 is secured. A suitable cap 84 is provided and surrounds the packing ring 85 and this cap is threaded on the A threads of the boss 80 and clamps the pack ing ring S5 between the outer end of the boss and the cap. A rectangular portion 86 is formed at the inner end of the shaft S1 and secured on this rectangular portion'is the agitator designated generally by the nu meral 87 comprising the hub 88, having the arms 89 extending therefrom.

1t will be apparent from the foregoing that in use the device is first assembled by placing the desired quantity of liquid within the chamber formed by the shell 2. rthe cooperating liquid is then placed in the bottle when the cap 21 is in the position shown in Fig. 3, and after the bottle has been filled to the desired point the same is then placed in the dome-shaped portion 10 of the shell 2 and the cap screwed in place. The stem 40 is then pressed downwardly as far as possible so as to force the washer 39 into engagement with the upper end of the bottle, and it will be seen that the device is held against accidental discharge as the two liquids cannot mingle until the device is manually opened. In this way it will be apparent that an extinguisher may be transported without danger of becoming inoperative through accident. As soon as it is necessaljy to put the device .in Operation, the

`point and the Vbottle is then uncovered by lifting the washer 39 from its position on lthe mouth thereof. Vrfhe whole is then inverted, Vand it will be apparent that the liquid within the bottle will mingle with the liquid in the chamber 1 and the gas caused thereby will force the liquid from the chamber through the hose, from whence it may be directed to the desired point. It will be evident that substantially the entire quantity of liquid will be forced from the extinguisher as the tube feeding` the hose is located at the lowermost point and thus forms a siphen action so long as there is any liquid within the device.

' 1t is to be-understood that when the extinguisher is not in use, the same iste, be shaken soV as vto agitate the chemicals and keep them at their maximum stage, thereby insuring the greatest possible efficiency of the extinguisher. In order to further assist in maintaining the mixture in the chamber 68 and maintain the contents thereof at their greatest efliciency so as to prevent crystalli- Zation and precipitation of the chemicals,

' the agitator S7 is periodically turned so as to scrape the bottom 78 of the extinguisher and thereby prevent the crystals from adhering to the bottom. Upon shaking the device it will be noted that the crystals thus described will be again dissolved and the same suspended in a solution.

TWhile in the foregoing there has been shown and described the preferred embodiment'of this invention, it is to be understood that such changes may be made in the com.

bination and arrangement of parts as will fall within the spirit and scope of the appended claims.
